Answer:
Step-by-step explanation:
Slope-intercept form is written in 
So, to solve, we must separate y onto one side and make its coefficient one.
Subtract 4x on both sides.
Divide both sides by the coefficient of 
, which is 3.
Simplify.
Rewrite this equation into standard form by changing the order of 
and 
Point-slope form is y - y1 = m (x + x1)
First you need to find m [slope] by subtract y2 and y1 and divide it by the outcome of x2 - x1
13 - (-9) = 22
-2 - 9 = -11
22/-11 = -2
Plug in the first point (as instructed) into the equation.
y - (-9) = -2 (x - 9)
Simplify the beginning.
y + [9] = [-2] (x + [-9])

Answer:
0.16666666666 or 16666666666/100000000000
Step-by-step explanation:
Answer: $102 per month
Step-by-step explanation:
15% off $120 means $120-(.15*$120) which is 120-18=$102. The .15 is the 15%, and 15% of 120 would be the whole multiplication.
Answer:
6/10
Step-by-step explanation:
all can be reduced to 2/5, except 6/10:
2/5
8/20=2/5 (divide out 4)
12/30=2/5 (divide out 6)
but not
6/10 = 3/5!
